-Assembly parser now properly check the size of the memory operation specified in intel syntax. So 'mov word ptr [5], al' is no longer accepted. -x86-32 disassembly of these instructions no longer sign extends the 32-bit address immediate based on size. -Intel syntax printing prints the ptr size and places brackets around the address immediate. Known remaining issues with these instructions: -Segment override prefix is not supported. PR16962 and PR16961. -Immediate size should be changed by address size prefix. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@189201 91177308-0d34-0410-b5e6-96231b3b80d8
